the latest edition of the book
Advanced Perl Programming
in an O'Reilly article.
"Around Easter last year, I finished writing the second edition of Advanced Perl Programming, a task that had been four years in the making. The aim of this new edition was to reflect the way that Perl programming had changed since the first edition. Much of what Sriram wrote in the original edition was still true, but to be honest, not too much of it was useful anymore--the Perl world has changed dramatically since the original publication.
The first edition was very much about how to do things yourself; it operated at a very low level by current Perl standards. With the explosion of CPAN modules in the interim, "advanced Perl programming" now consists of plugging all of the existing components together in the right order, rather than necessarily writing the components from scratch. So the nature of the book had to change a lot.
